Typical Performance Characteristics
Application Information
The LM6152/LM6154 is ideally suited for operation with
about 10 kΩ (Feedback Resistor, R
and the negative input terminal.
With R
close loop gain of 10 or less, an additional small compensa-
tion capacitor (C
in order to achieve a reasonable overshoot (10%) at the
output by compensating for stray capacitance across the
inputs.
The optimum value for C
mentally with a trimmer cap in place since its value is de-
pendant on the supply voltage, output driving load, and the
operating gain. Below, some typical values used in an invert-
ing configuration and driving a 10 kΩ load have been tabu-
lated for reference:
In the non-inverting configuration, the LM6152/LM6154 can
be used for closed loop gains of +2 and above. In this case,

Because of the unique structure of this amplifier, when used
at low closed loop gains, the realizable BW will be much less
than the GBW product would suggest.
The LM6152/LM6154 brings a new level of ease of use to op
amp system design.
The greater than rail-to-rail input voltage range eliminates
concern over exceeding the common-mode voltage range.
The rail-to-rail output swing provides the maximum possible
dynamic range at the output. This is particularly important
when operating on low supply voltages.
The high gain-bandwidth with low supply current opens new
battery powered applications where higher power consump-
tion previously reduced battery life to unacceptable levels.
The ability to drive large capacitive loads without oscillating
functional removes this common problem.
To take advantage of these features, some ideas should be
kept in mind.
The LM6152/LM6154, capacitive loads do not lead to oscil-
lations, in all but the most extreme conditions, but they will
result in reduced bandwidth. They also cause increased
settling time.
